habitat for pest organisms; and
    (3) Cultural practices that enhance crop health, including selection 
of plant species and varieties with regard to suitability to site-
specific conditions and resistance to prevalent pests, weeds, and 
diseases.
    (b) Pest problems may be controlled through mechanical or physical 
methods including but not limited to:

pests, weeds, or diseases: Provided, That, the conditions for using the 
substance are documented in the organic system plan.
